Preventing Myopia Regression with Corneal Cross-Linking
Hello, this is Gangnam Bright Eye Clinic.
Today, we will discuss 'myopia regression,' a concern related to vision correction surgery that many people are interested in.
Many people seek to restore their original vision through vision correction surgery, but there are concerns about myopia regression, a phenomenon where vision deteriorates again after surgery.
What is myopia regression?
Myopia regression refers to the phenomenon where corrected vision returns to its previous state.
Recently, there have been cases where patients who have undergone vision correction surgery visit the ophthalmologist again due to decreased vision.
In surgeries that correct refractive errors of the cornea using a laser, myopia regression can occur as the cornea regenerates and returns to its original state after surgery.
It is known that the higher the amount of myopia before surgery, the greater the possibility of regression.
The Necessity of Corneal Cross-Linking
There is a way to help suppress myopia regression and secure long-term stability of vision: corneal cross-linking.
This method is performed immediately after laser vision correction surgery (LASIK, LASEK, SMILE LASIK, etc.) for vision correction.
After applying riboflavin (vitamin B2) to the cornea, corneal collagen cross-linking is performed to strengthen the binding force of the collagen that makes up the cornea.
This helps maintain the corneal stiffness to the level before surgery.
Especially in cases of high myopia or congenitally thin corneas, even with the same amount of residual corneal thickness after surgery, it is relatively safe from side effects such as corneal ectasia compared to other surgeries.
Limitations of Corneal Cross-Linking
Although corneal cross-linking helps suppress myopia regression, it cannot be performed if LASIK or LASEK surgery is not possible due to poor corneal condition.
It can only be performed after determining whether laser vision correction surgery is suitable through about 50 tests before surgery.
Smart SMILE LASIK and Lens Implantation
Smart SMILE LASIK and lens implantation are ways to reduce the possibility of myopia regression.
Smart SMILE LASIK surgery uses a femtosecond laser to pass through the corneal epithelium without removing it, so there is no thinning or regeneration process of the corneal epithelium.
Therefore, even patients with thin corneas can maintain stiffness through corneal cross-linking, which greatly reduces the probability of myopia regression due to Smart SMILE surgery.
Lens implantation is also effective in reducing the risk of myopia regression by preserving the cornea as it is.
Conclusion
Although rapid recovery after vision correction is important, systematic examination is essential if you want to maintain healthy vision for a long time after surgery.
Even with the same surgery, good results can be obtained only when methods to increase safety, the skills and know-how of the medical staff, and consistent post-operative care are combined.
